Foxplay is already a Group One winner, taking out the Queen Of The Turf Stakes at Randwick during the last Sydney autumn carnival under Kerrin McEvoy who takes the ride on Saturday.

The mare hasn't yet recaptured her autumn winning form but did finish second to Winx first-up in the Warwick Stakes and was third to the great mare in the George Main Stakes at Randwick in September.

She followed up with a fourth placing in the Epsom Handicap before finishing seventh in the Tristarc Stakes at Caulfield two weeks ago.

McEvoy said Foxplay would appreciate stepping up to 1600m on Saturday after finding the opposition too slick over 1400 last time.

"It was too firm for her at Caulfield the other day and she wobbled around the bend," McEvoy said.

"Plus the 1400 metres was just a bit sharp for her but she stayed on well.

"A mile at Flemington with a little bit of juice in the ground is going to be perfect and at her best she's going to be very hard to beat.

"But it's a big field with many, many chances."

The Myer Classic is an open betting race with first-up Tristarc winner Global Glamour and three-year-old filly Shoals sharing top billing at $5 ahead of Silent Sedition at $7.50 with Foxplay on the next line at $8.50.
